1 Slacker’s Guide to Thoracic Gross Anatomy Prepared by Mike Ori
2 Caveat EmptorAs with all slackers guides, I have omitted, condensed, and misunderstood information so don’t complain if I got something wrong, after all, you’re a slacker.Also, it goes without saying that the faculty has not vetted the information in any way. Always refer to their notes and lectures for the last word.
3 CT and SuchYou’re probably best off working on an interactive system tryCPR Radiograph key from Slice-o lecture is important
